I don't see any significant colour cast. So if you want to experiment with real filters without breaking the bank, these are a good buy. The filter sleeves are beautiful and the whole product presentation/packaging exudes quality.

Fits...

Clean workmanship...I am still testing it.

The grey filter comes in a sturdy protective case and fits neatly into my rectangular filter holder. There are no flaws whatsoever in the optical properties. A satisfied customer thanks.

I was completely satisfied.Darken the scene 10 light levels so you can take long exposures in daylight in total comfort. It is made of glass and looks good quality. I used.Comes with a leather case, lined with a soft fabric inside; velvet type which comes very well so you can wear it without fear of scratches.

All in all, a good product. The adapter rings only have one thread, which I can screw onto my lens (49mm in my case). If I want to mount a polarising filter, etc., I first have to put on the screw filter and then the adapter.What I also noticed is that the adapter ring sits very smoothly in the filter holder. It's like a steering wheel that you can turn several times without any problems. A small rubber lip (on the adapter or on the holder) would possibly help here.Still a good product!

I am very pleased with these filters, and can not find any degradation in my images using them.

I was really looking forward to it, everything is packaged beautifully and with high quality, so you can't say anything really great

This is ideal for my photography as I only need one set of filters to fit all my lenses.

bought the rectangular filter set directly from K&F. Since I have worked with screw filters in the past and had the problem with vignetting when screwing several filters on top of each other, I have wanted to buy a rectangular filter set for a long time. Since the sets from NISI, Haida and other well-known manufacturers are very, very expensive, as a hobby photographer I was looking for a cheaper alternative. When I saw several reviews on YouTube, I decided on the K&F set, which is half the price of Haida and CO. I have absolutely no regrets about my decision. The filter holder is very valuable and well thought out. I particularly like how the polarizing filter is attached to the holder and how it can be adjusted using the small wheel. The filters themselves are made of optical glass and show no color cast and are also well coated. Another positive aspect is that the filters have a plastic frame with a tab. This allows the filters to be inserted and removed without annoying fingerprints. A bag is included to store and transport the holder and the filters in it. Also included are various adapter rings for different filter thread diameters. As a landscape hobby photographer, I no longer want to do without the advantages over screw-on filters. I give a clear purchase recommendation for amateur photographers and professionals too! I wasn't expecting such excellent quality for this price. It's amazing what K&F delivers here.
